Full Cloudron Backups are failing on Cloudron version 7.7.0

Please do not run a full apt upgrade as such, as it may update packages which Cloudron relies on and could render the instance broken. Explicitly updating the kernel should be ok though.

Another customer of ours hit this issue. I wonder what has changed that suddenly CIFS requires SEAL encryption. We have made this default now for next release in any case.

@girish I don't think it requires seal encryption.

I believe using seal encryption causes a different code path to be taken that avoids the underlying bug but it is not the presence or absence of seal encryption in and of itself that I believe fixes the issue.

After a kernel upgrade this works fine without seal encryption though I have now enabled it as it seems like a good idea to have anyway so making it the default is probably a good idea but as long as Ubuntu 22.04's default kernel version is 5.15.0-102 this issue will likely still occur.
